Abstract: Système utilisant une bobine multiple sur laquelle sont enroulées par groupes des canalisations souples portées par des structures articulées (8, 9). Les groupes de canalisations souples sont reliés à une extrémité à des canalisations souples (4) de produits et commodités en provenance du fond marin et, à l'autre extrémité, à des blocs de connexion (10, 11) que l'on peut relier à des plaques de connexion (15, 16, 17, 18) sur au moins une tourelle de connexion (13, 14) à bord d'un navire. Etant donné que les connexions sont redondantes, il est toujours possible de repositionner un groupe de canalisations souples pendant qu'un autre groupe est connecté, ce qui confère au système de transfert (2) une totale liberté de mouvement.

Title: Procede de production d'acide terephtalique de purete monomerique
Inventor: VOVK LUDMILA STEPANOVNA
IPC: C07C51/43
Filed: 1996-05-08
Abstract: Cette invention se rapporte au domaine de la synthèse organique et pétrochimique industrielle, et concerne, en particulier, un processus continu de production d'acide téréphtalique de pureté monomérique. Cette invention propose un processus industriel de fabrication qui permet d'améliorer la qualité de l'acide téréphtalique et de réduire les pertes spécifiques en acide acétique par la combinaison de deux processus interdépendants d'oxydation et de recristallisation dans un solvant unique eau-acide acétique. Le processus d'oxydation est effectué à l'aide d'une cascade de deux réacteurs montés en série et à des températures modérées, en présence d'un catalyseur se composant d'un mélange de métaux (Co, Mn, Ni, Na, Li, K) et d'un mélange de composés de brome, lesquels mélanges comportent des liaisons ioniques et covalentes, et ceci dans des conditions expérimentales déterminées. Les produits intermédiaires sont éliminés de l'acide téréphtalique lors de l'étape de recristallisation de ce dernier en acide acétique dans des conditions expérimentales déterminées. Les liqueurs mères sont ensuite remises en circulation dès que les acides téréphtaliques brut (filtrat 1) et pur (filtrat 2) ont été séparés respectivement lors de la première et de la seconde étape d'oxydation.

Patent CA-2006472-A1 (CA)
IPC: B65H29/12
Filed: 1989-12-21
Abstract: A signature handling apparatus includes a first conveyor which sequentially moves signatures to a discharge station.          At the discharge station, the signatures are sequentially transferred to a receiving conveyor.  A corrugator assembly is located at the discharge station to stiffen the signatures by forming corrugations which extend between leading and trailing end portions of the signatures.          Although the corrugations are only temporarily maintained in the signature, the corrugator assembly is close enough to the receiving conveyor so that a corrugation is maintained in a signature as a leading end portion of the signature moves to the receiving conveyor.  Thus, the corrugator assembly is spaced from the receiving conveyor by a distance which is less than the distance between the leading and trailing end portions of the signatures.

Patent CA-2017718-A1 (CA)
IPC: B63H1/16
Filed: 1990-05-29
Abstract: The present invention provides for a propulsion apparatus for fluid medium comprising an open-ended sleeve having an inlet and outlet for flow through of fluid and a series of cooperating blades positioned within and along the sleeve. Each of the blades has a leading edge and a trailing edge and the blades are fixed to rotate with the sleeve and cause a progressive acceleration of fluid from the inlet to the outlet with rotation of the sleeve thereby providing thrust for propulsion. Adjusting means and are provided interconnecting the blades for pitch adjustment of the leading edges and trailing edges of the blades.  The blades cooperate to define a fluid path to accelerate a fluid from the inlet to the outlet to thereby provide thrust for propulsion as the sleeve is rotated.  The apparatus of the present invention provides forward and reverse speed of propulsion independent of the speed and rotation of the driving mechanism whereby adjustment of the blades at a fixed speed accelerates or decelerates the propulsion effort.

Abstract: ABSTRACT OF THE DISCLOSURE         A diversity system comprising two receiving branches for receiving a radio signal including a data signal portion and a training signal portion propagating through a multipath, wherein,  in  each  branch,  a  transmission  property  of  a propagating path thereto is estimated from the training signal portion  received,  the  transmission  property  comprising components  significant  to  an  equalizer  and  remaining insignificant components.  A branch selectors selects, as a selected branch, a specific one of the branches according to the maximum value of a power ratio between the power of the significant components and of the insignificant components, and the equalizer equalizes the data signal portion received at the selected branch to produce an equalized signal as a resultant signal of the system.  In order to reduce the effect of the property estimation from the data signal portion, the branch selector selects, as a selected branch, a particular one of the branches according to the maximum value of a power sum of the power of the significant components and the insignificant components, when another ratio of the power of the significant components and the power sum is larger than a predetermined value.

Title: Applying drywall tape to drywall joint
Inventor: VACCARO ANTHONY
IPC: B65C9/00
Filed: 1990-09-06
Abstract: ABSTRACT OF THE DISCLOSURE             Method and apparatus for applying drywall tape to joint compound along a drywall joint and simultaneously spreading the compound contacted by the tape. The tape in roll form is delivered to a tape applicator from a tape dispenser fixed to a user's belt. The dispenser pivots to follow movement of the tape applicator. The tape applicator has a support frame including guide posts for directing the tape onto a roller. A force is continually applied to the tape to resist tape movement relative to the guide posts and roller. The roller is pressed against the tape with sufficient force to spread the jointcompound beneath the tape and simultaneously rolled over the tape thereby overcoming the movement-resisting force, spreading the joint compound and and embedding the tape along the joint. A cutting blade extends forwardly over the roller ant trails the roller as the tape is applied. When taping is complete, the support structure is manipulated so that the movement-resisting force tensions the tape over the roller and the support structure is pivoted about theroller to engage the cutting blade with the tape.
